What is Stock Price X402?

Stock Price X402 is an MCP server that provides real-time stock quotes — price, change percentage, volume, market cap, and company name — for all major US and international exchanges. It uses the x402 micropayment protocol (USDC on Base L2) for pay-per-call access with no API key, no signup, and no rate-limit walls. It is part of the klymax402 marketplace.

How to use Stock Price X402?

Add the server URL https://stock-price.api.klymax402.com/mcp to your MCP client configuration (Claude Desktop, Cursor, ElizaOS, etc.). Then use the tool finance_get_stock_price with a symbol parameter (e.g., AAPL, TSLA). x402-aware HTTP clients can also call the /api/quote endpoint directly.

常见问题

1

What is the x402 payment protocol?

x402 is an HTTP-native pay-per-call protocol that uses USDC on Base L2. It eliminates the need for API keys, signups, or subscription plans — the client pays per request automatically.

2

Do I need an API key to use Stock Price X402?

No. The server uses x402 for payment, so there is no API key, signup, or rate-limit wall. Any x402-aware client handles the payment cycle automatically.

3

What network and asset does payment use?

Payments are made in USDC on the Base L2 network (chain ID `eip155:8453`), facilitated by Coinbase CDP (primary) and PayAI (fallback).

4

How much does each call cost?

Each call to `finance_get_stock_price` costs $0.002 USD (paid as USDC on Base).

5

What exchanges and tickers are supported?

The server supports all major US and international exchanges. You can query any standard stock ticker symbol (e.g., AAPL, TSLA, MSFT, GOOG). Crypto and currency tickers are not supported by this server.
